Hi, I'm selling my car shortly (a 2002 MY A3 8L) which I fitted almost from new with a Becker Sat Nav HU. I want to keep that, and as I sold the Concert 2 long ago, I need to source an Audi head unit to replace it prior to sale. My question is, will the older Concert 1 units work in my CANBUS car? Will the station info be displayed in the DIS etc? Or, do I need a 2002 vintage CANBUS head unit like the original Concert 2? Any other ideas for compatible single DIN Audi HU's?
